When purchasing an industrial soft starter, providing complete technical information helps manufacturers recommend the right solution and avoid delays during project execution.
Before requesting a quotation, customers should prepare key motor, load, and application information.

1. Motor Information Required for Soft Starter Selection
Before selecting a soft starter, customers should provide:
- Motor power (kW)
- Rated voltage
- Rated current
- Frequency
- Motor starting method
Example:
A 10kV, 1000kW motor requires a medium voltage soft starter solution designed for the specific motor parameters.
2. Load Type and Application Details
The same motor power may require different soft starter configurations depending on the load.
Customers should provide:
- Pump
- Fan
- Compressor
- Conveyor
- Crusher
- Mill
The load characteristics affect:
- Starting torque requirement
- Acceleration time
- Starting current limitation

3. Starting Conditions
Manufacturers need to understand the operating conditions:
- Required starting time
- Starts per hour
- Load inertia
- Continuous or intermittent operation
This information helps determine the correct soft starter capacity.
4. Electrical System Requirements
Customers should confirm:
- Voltage level
- Short circuit capacity
- Protection requirements
- Communication protocol
Common communication options include:
- Modbus
- Profibus
- Ethernet communication
5. Installation Requirements
For industrial projects, installation conditions are also important.
Please provide:
- Indoor or outdoor installation
- Ambient temperature
- Protection level requirement
- Cabinet dimensions
- Cooling requirements
6. Project Information
For EPC and industrial projects, additional information is recommended:
- Project location
- Industry
- Project stage
- Required delivery date
- Technical specification
This helps manufacturers provide a complete proposal.
